Magic of Rembrandt's Painting Technique Revealed

To figure out Rembrandt's painting secret, scientists used computer rendering to match photos of current models (and a scientist) with four of Rembrandt's portraits. They manipulated four regions of the portraits: regions centered about each eye, on each side of the chin, and the region where the collar meets the skin of the neck.Credit: Steve DiPaola, James Enns, Caitlin Riebe.

Rembrandt's paintings have transfixed viewers for centuries,
but now a new study reveals a scientific explanation for their calming beauty. By
painting more detail in and around the eyes of his subjects, Rembrandt tapped
into an innate human attraction to the face. This creates a more calming and
immersive experience for the viewer.

Steve DiPaola of the University of British Columbia (UBC)
suggests Rembrandt Harmenszoon van Rijn may have pioneered a technique that
guides the viewer's gaze around a portrait, creating a special narrative and "calmer" viewing experience. He and his colleagues detail their findings in the current issue of the Massachusetts Institute of Technology's arts and sciences journal Leonardo.

Renaissance
artists used various techniques to engage viewers, many incorporating new
scientific knowledge on lighting, spatial layout and perspectives. To isolate
and pinpoint factors that contribute to the "magic" of Rembrandt's
portraits, DiPaola used computer-rendering programs to recreate four of the
artist's most famous portraits from photographs of himself and other models.
Replicating Rembrandt's techniques, DiPaola placed a sharper focus on specific
areas of the model's face, such as the eyes.

Working with a team from the Vision Lab in UBC's Department
of Psychology, DiPaola then tracked viewers' eye movements while they examined
the original photographs and the Rembrandt-like portraits.

"When viewing the Rembrandt-like portraits, viewers
fixated on the detailed eye faster and stayed there for longer periods of time,
resulting in calmer eye movements," DiPaola said. "The transition
from sharp to blurry edges, known as 'lost and found edges,' also directed the viewers'
eyes around the portrait in a sort of narrative."

The study is the first to scientifically verify the impact
of these "eye-guiding" techniques on viewers and to attribute its
origin to Rembrandt.

The viewers also preferred portraits with this "eye-guiding
narrative" to the original photographs with uniform details across the
tableau.

"Whether he observed how his own eyes behaved while
viewing a painting or if he did it by intuition, Rembrandt incorporated an
understanding of how the human
eye works that has since been proven accurate," DiPaola said.
